Spring 2.5

[murygin]

I would like to run activiti 5.0.rc1 together with Spring 2.5.6. I can't switch to Spring 3.0. Creating org.activiti.spring.ProcessEngineFactoryBean throws a org.springframework.beans.factory.BeanCreationException. nested exception is java.lang.reflect.MalformedParameterizedTypeException.

I added the following jars to my Spring 2.5 setup:

• activiti-engine-5.0.rc1.jar


• activiti-spring-5.0.rc1.jar


• mybatis-3.0.2.jar


• h2-1.2.145.jar

Stacktrace:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'processEngine' defined in class path resource [sernet/gs/server/spring/veriniceserver-activiti.xml]: Initialization of bean failed; nested exception is java.lang.reflect.MalformedParameterizedTypeException

Could you post your Spring config?

[murygin]

Here is the activiti related file from the Spring configuration. It's copied from the User Guide. I changed spring-tx-3.0.xsd to spring-tx-2.5.xsd.

Activiti is indeed tested with Spring 3.0+ only.
But looking at the XML, it should be ok.

Apparently this exception occurs when a mixture of spring 3.0 and spring 2.5.6 (or lower) are on your classpath.
